Among the 50 most recent science and engineering rounds, the only disclosed deal above $100M is CDB Aviation’s $700M on 2025-05-20; the next-highest disclosed amounts sit far lower (e.g., The Exploration Company at $158M on 2024-11-18 and Climeworks at $162M on 2025-07-02), while several recent rounds cluster in the $10M–$50M band (e.g., Qedma $26M on 2025-07-03; OpenAirlines $48M on 2024-11-14; Starfish Space $29M on 2024-11-13). The disclosures also show a stage/coverage split: 20 of 50 rows are “Series Unknown,” and 2 of 50 are “undisclosed,” leaving a minority with named stages (e.g., Quantum Machines $170M in Series C on 2025-02-25; Electra.aero $115M in Series B on 2025-04-21).
Date coverage runs from 2024-10-22 (Turnover Labs, $1M) to 2025-11-22 (CisLunar Industries, undisclosed). Several geography clusters appear via the same broader metros recurring within the list: Los Angeles is repeatedly represented across multiple stages and round sizes (e.g., Mote $7M on 2025-03-04; Inversion Space $44M on 2024-11-20; also Flight science 2025-03-25 at $2M), and Dublin appears twice (CDB Aviation $700M on 2025-05-20 and Fusion Fuel $4M on 2025-07-23).

Frequently asked
What stands out in deal size—what’s the largest disclosed round, and how does it compare to the rest of the list?
CDB Aviation’s $700M disclosed round on 2025-05-20 is an outlier: it’s the only disclosed amount above $100M in these 50 rows (e.g., Climeworks $162M on 2025-07-02 and The Exploration Company $158M on 2024-11-18 are the next tier).
How much of the dataset is missing stage/amount details, and does that affect interpretability of comparisons?
Stage labels are incomplete in 20/50 rows marked “Series Unknown” (e.g., Air Space Intelligence $350K on 2025-08-15; Procureship undisclosed on 2025-06-11). Amounts are also missing for 2/50 rows (CisLunar Industries on 2025-11-22 and Astro Mechanica on 2025-08-20), so largest/smallest comparisons must rely on disclosed amounts only.
Are there any clear temporal edges, and which companies define the newest and oldest disclosed dates?
The most recent round date shown is 2025-11-22 (CisLunar Industries, undisclosed). The oldest date shown is 2024-10-22 (Turnover Labs, $1M), bracketing the list across roughly one year.
Do specific locations cluster across multiple companies or round sizes (beyond single entries)?
Los Angeles shows repeated appearances across different round sizes and stages: Flight Science raised $2M on 2025-03-25 (Los Angeles) and Mote $7M on 2025-03-04 (Los Angeles), while Inversion Space closed $44M on 2024-11-20 (also Los Angeles). Dublin likewise reappears with CDB Aviation’s $700M on 2025-05-20 and Fusion Fuel’s $4M on 2025-07-23.
What stage mix is actually visible in disclosed rounds, given the prominence of “Series Unknown”?
Named stages appear but are outnumbered by missing stage labels: “Series Unknown” accounts for 20/50 rows. Among labeled rounds, examples include Quantum Machines in Series C ($170M on 2025-02-25), Electra.aero in Series B ($115M on 2025-04-21), and multiple Series A deals such as Qedma $26M on 2025-07-03 and Pangea Aerospace $25M on 2025-03-18.
